. The present invention is a division of my prior Yparent application Serial No. 410,346, filed November 29, 1929, now j Patent'No.V 1,871,295, of August 9,1932, and it willbe understood that the main frame structure 2 p y1,906,507l

contemplated for use with the embodiments of the present invention herein exemplified, may be the same as that described as the ap proved embodiment of the invention in the aforesaid parent application.

The combined cylinder saddle` and bumper beambracket structure, comprises, in an integral casting, a saddle 10, a bumper bracket 11, a truck center pin 12, guide yoke supports 13, a cross tie 14, for the guide 'Walls 19y to provide flanges 28, having bolt holes 24, for attachment of the side frame members 1, and cylinder castings to the cylinder saddle. The Vtop Wall 21 of the saddle is extended beyond the end Walls 19 to provide fianges 25, having bolt holes 26 for the attachment of aflat plate 27 of smoke box 28.

The truck center pin 12 projects verti cally downward from the horizontal bottomwall 20 of the saddle.

.-,Thebuinper beam bracket 11 is connected to the front end Wall 19 of the saddle by afhorizontal Web 29, and longitudinal vertical flanges 30, joining the side Wallsv 1 8, and having bolt holes 31, for bolting the side frame members `1 to the saddle. It will be understood that a bumper beam` (not shown) may be either detachably bolted to thel bracket 11 or integrally `formed `therewith. l

lExtending to the rear of the cylinder-saddlevis albox shaped structure 32, comprising vertical side Walls 33, joined toA andin alignment with the side Walls 18, and their rear flanges'f23, and having vbolt holes 34,..for bolting the side frame ;members 1 tothe casting. The aforesaid brake cylinder supports 15, for theattachment of the usual brake cylinders (not shown) are formed on the Walls 33. The rear:V structure 32, also comprises a bottom Wall 35 joinedto and in alignment with the Wall 20; longitudinal reinforcing ribs 36; and a rear Wall 37, which extends vertically above, and laterally beyond, the side walls 33,to provide, at its opposite-ends, the aforesaid guide yoke supports 13, and a cross tie 14 therefor. The Wall 14 .provides a support to which a bracket of any 4Well knowndesign may be secured, and extendedupwardly forsupporting the waist of the locomotive boiler to :the rear of the-smoke box.

'Extending to the rear of the :box shaped structure 82, are vertiealflanges 38, fformed With the aforementioned brake lever fulcrums 17, and bolt holes 39, for attachment of the casting to the side frame members 1. Extending rearwardly of the rear Wall 37, is a horizontal flange 40, to which the top plate 5, of the frame, is connected by Welding (not shown). Vertical reinforcing ribs 4.1, `42 and 43, similar to ribs 3G, are provided between the Walls 18 and 19 and the bracket 11.

. Each cylinder casting 50 comprises a cylinder 51; a distribution valve chest 52; a flat top Wall.53,having end flanges 54, anda side flange 55, `the said flanges having bolt holes 56, formed therein, for attachment of the fiatbottomplate 27 of thesmoke box 28, andthe flanges 54,1natching Withithe flanges of the saddle. An 'inlet passageway 57, leading from an adjacent opening 58, formed in the bottom of' the smokebox, fonsupplying steamto the valve chest, and anV outlet exhaust passageway 59,leading from the valve chest to the adjacent cylinder saddle passageway 22, are formed in the cylinder casting. l By referring to'Fig. 3 of the drawings, it will `be seen that the .steam` suppiy l passageway 57, yleading through the cylinder casting from the valve chest to the opening 58, located inwardly of the side of the smoke box, thus avoids `the use of steamA supply pipes outside ofthe smoke box and valve chest, las in former practice.

The :vertical ifianges are offset 'at their forward ends providing laterally extending' shoulders `30m against which the; front ende of the sideframef members 1- abut. The cylinder castings -are formedwith inner Walls 60, ithef upper parts` of which Walls bear against, themside Walls 18 `ofthe cylinder saddleandtheir flanges 23, and the lower parte of which are odset to provide spaces adjacent the walls 18, through. which. spaces the side framemembers Lextend. 4Bolts 61 are passed through the walls 60of the cylinder castings, and the flanges123of the cylin` der saddle respectively, and lthrough `the side frame members, securing the parts together. The lower edges of the forward ends ofthe side frame members 1 are` provided With lateraldianges 1a which extend l along :the lower edges of the Walls 6() and the `Walls 18 and theirv flanges 23, therebynma'kingffor a more secufrejointure ofthe parts.
